The method generally includes the steps of (A) determining co-located motion information for a plurality of co-located sub-blocks in a co-located macroblock of the video bitstream, (B) storing the co-located motion information for (i) at least a first three of the ... 06/09/05 - 20050123054 - Macroblock level adaptive frame/field coding for digital video content A method and system of encoding and decoding digital video content. The digital video content comprises a stream of pictures which can each be intra, predicted, or bi-predicted pictures. Each of the pictures comprises macroblocks that can be further divided into smaller blocks. The method entails encoding and decoding each ... 06/09/05 - 20050123053 - Systems and methods for media summarization A stream of ordered information, such as, for example, audio, video and/or text data, can be windowed and parameterized. A similarity between the parameterized and windowed stream of ordered information can be determined, and a probabilistic decomposition or probabilistic matrix factorization, such as non-negative matrix factorization, can be applied to ... 06/09/05 - 20050123052 - Apparatus and method for detection of scene changes in motion video Apparatus and method for new scene detection in a sequence of video frames, comprising: a frame selector for selecting a current frame and one or more following frames; a down sampler, associated with the frame selector, to down sample the selected frames; a distance evaluator to find a statistical distance ... 06/02/05 - 20050117653 - Loop deblock filtering of block coded video in a very long instruction word processor This invention is applicable to filtering block artifacts of macroblock and block oriented video compression. This invention computes all possible filter results speculatively and simultaneously in parallel, computes conditions for application of corresponding filter results simultaneously in parallel, and writes filter results to memory conditionally dependent upon computed corresponding conditions. ... ### FreshPatents.com Support |
